Tam sim no, tsis yog lub tshiab tshaj tawm cov xov tooj ntse yeej txhawb hom-C txuas sib txuas, tab sis kuj siv cov khoos phis tawm, cov koob yees duab digital, tus neeg hais lus ntse, cov khoom siv fais fab thiab lwm yam khoom siv kuj tau pib siv hom-C USB cuam tshuam. Niaj hnub no' s tsheb Teb lub teb kuj tseem tau ua tiav txawv teb, hloov chaw USB-A. Tesla tus qauv tshiab 3 yuav siv USB-C chaw nres nkoj. Ib qho ntxiv, Apple tau hloov tag nrho nws lub MacBook laptop mus rau lub ntshiab USB Type-C interface kom tso cai rau cov neeg siv hloov ntaub ntawv lossis them. Muaj txawm tias kev lag luam lus xaiv hais tias Apple tseem yuav siv USB hom-C interface ntawm iPhones yav tom ntej.
Kev hloov pauv loj tshaj plaws ntawm USB4 tshiab yog kev qhia ntawm Thunderbolt raws tu qauv kev qhia tawm los ntawm Intel rau USB-IF. Los ntawm kev sib txuas ob txoj haujlwm, qhov kev xa xov hluav taws xob tau nce ob zaug mus rau 40Gbps, thiab nws tuaj yeem txhawb nqa los ntawm kev sib tw cov tshuab sib kis. Ntau cov ntaub ntawv thiab teeb tsa kev cai, xws li PCI Express thiab DisplayPort. Ib qho ntxiv, thaum qhia cov kev cai tshiab hauv paus, USB4 tseem tseem muaj kev coj ua zoo, thiab rov qab tau tshaj nrog USB3.2 / 3.1 / 3.0 / 2.0 thiab Thunderbolt 3.
Nws tseem muaj tseeb tias USB4 tau dhau los ua tus qauv USB nyuaj tshaj plaws, kom cov neeg tsim qauv nkag siab txog cov txheej txheem kev qhia ntawm USB4, USB3.2, USB2.0, USB hom-C thiab USB lub hwj chim xa tawm. Ntxiv rau, cov neeg tsim qauv kuj yuav tsum nkag siab txog PCI nthuav qhia thiab DisplayPort cov ntsiab lus, nrog rau lub siab txhais cov ntsiab lus tiv thaiv (HDCP) thev naus laus zis uas yoog rau USB4 DisplayPort hom.
Tab sis qhov kev hloov pauv loj tshaj plaws uas peb tau pom yog tias hnub no USB cov ntaub ntawv cable tau pib xav tau daim ntawv thov chips. Yog tias koj yuav tsum siv USB hom-C cov ntaub ntawv cable kom ua tiav cov ntaub ntawv xa mus tau zoo, lub suab txhais tau zoo dua, thiab lub zog ntawm cov khoom siv fais fab muaj peev xwm, muaj peev xwm ntawm cov nti xav tau los pab txhawb nqa ntau qhov kev sib txuas lus hauv high-speed interface, suav nrog USB4, DisplayPort 1.4a TX, PCI Express thiab Thunderbolt 4, thiab lwm yam Nws yog khi rau xav tau kev pab ntawm lub nti. USB4 router IP tsim muaj kev sib txuas zoo ntawm txhua qhov kev txhawb nqa tau los ntawm nti.
Puas yog USB4 daim npav tseem ceeb?
USB4 cable yuav tsum muaj IC los xyuas kom meej qhov zoo ntawm lub teeb liab xa xov hluav taws xob siab, thiab lwm qhov yog khaws cov ntaub ntawv tseem ceeb txog ntawm cable, nrog rau seb nws tuaj yeem txhawb 3A rau 5A nrog lub tsheb tam sim no. Vim tias cov teeb liab kis tau nrawm nrawm dua tam sim no, qhov xa hluav taws xob ceev tshaj plaws xa mus txog 20Gbps, thiab cov xov hlau tsis tuaj yeem luv. Txhawm rau kom ntseeg tau cov teeb liab zoo, cov chips nrog cov haujlwm xws li Re-timer thiab Re-driver feem ntau ntxiv. Re-timer yog Qhov kev ua haujlwm ntawm rov qab cov ntaub ntawv, Re-tsav tsheb txhim kho qhov zoo thiab tau txais kev taw qhia. Qhov hom IC no muaj peev xwm ua kom paub tseeb thiab muaj kev sib kis tau ntawm cov kev taw qhia kev kub ceev hauv qhov kev ncua deb.
Kuj tseem muaj ib hom hu ua E-mark chip (Dabteb yog E-MARK nti ntawm TYPE-C? ntawm lub cable, nws kuj Koj tuaj yeem paub seb puas txhawb nqa qhov hluav taws xob tuaj yeem dhau 3A, kom koj tuaj yeem paub qhov txawv hluav taws xob loj thiab cov kab hluav taws xob hauv qab 3A.
Hauv USB 3.0 lub caij nyoog, qhov kev xa tawm ntau tshaj yog 5Gbps, thiab lub thauj khoom tam sim no yuav tsis tshaj 3A, yog li cov ICs saum toj no tsis xav tau. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho cov khoom lag luam, ntau daim ntau thiab ntau daim ntawv thov yuav siv rau cov khoom lag luam
USB4 koom ua ke ntau yam ntawm kev cai rau Hom-C interface. Nyob rau yav tom ntej, phau ntawv siv koos pij tawj, xov tooj ntawm tes, kev ua si sab nraud, koob yees duab, thiab cov saib xyuas uas peb siv yuav txhua tus siv cov ntaub ntawv xov xwm sib koom ua ke, uas yuav coj ntau rau peb lub neej. Nws yooj yim, koj tsis tas yuav thab kom nkag siab txog ntau yam kev cuam tshuam rau yav tom ntej, thiab koj tsis tas yuav nqa ntau yam kev sib txawv ntawm cov cable thaum koj tawm mus. Ib tus cable tuaj yeem daws txhua yam teeb meem.
